ATTORNEYS Patented `lan. 31, 1933 ELMER GL. OVERLY, OF GREENSBURG,PENNSYLVANIA ENVELOPE CONSTRUCTION Application led April 23, 1931,Serial No. 532,170. Renewed October 31, 1932.

rlhis invention relates to combination envelopes of the kind used formailing articles, such as automobile license plates and registrationcards, or catalogues and letters, in a a single package, which articlesare subject to dilierent postal rates.

rlhis invention includes a large or main envelope, of the well-knowncommercial open end type, and a smaller envelope of preferio ably theopen side type, provision being made to permit the two envelopes to besubsequently assembled so that the well-known methods and machines Jforthe manufacture of such envelopes may be employed. le ln carrying outthe invention the larger envelope is provided with a slot, in one of itswalls, through which the smaller envelope is inserted. The slot ispreferably formed in the seam, of one of its walls, commonly 2e known asthe center seam, said seam being left unsealed 'for part of its lengthto provide said slot.

In order to seal the smaller envelope, the seal ap thereof is pastedagainst the wall of the larger envelope. Provision is also made to sealthe slot through which the smaller envelope is inserted. To this end oneof the envelopes, preferably the smaller one, is provided with a gumstripe whereby the upper end of said smaller envelope is secured tothebody of the larger envelope adjacent to the slot.

Other objects and advantages will hereinafter appear.

In the drawings forming part of this specification Figure 1 is a viewshowing the envelope assembled and closed;

Figure 2 is a transverse section on a larger scale taken on the line 2-2of Figure 1 and showing the smaller envelope partly removed;

Figure 3 is a view showing both envelopes open and the smaller one beinginserted into the larger one;

Figure 4 is a view similar to Figure 1, eX- cept that the smallerenvelope illustrated therein is considerably larger than the oneillustrated in Fi ure 1, this combination envelope being a apted for usein mailing 5o catalogues and letters;

Figure 5 is a view illustrating a modiication of the combinationenvelope; and

Figures 6 is a view similar to Figure 5 and shows the smaller envelopeinserted in place.

Similar reference numerals represent similar partsin the various views.

rl`he combination envelope 5 includes a large envelope 6, of the openend type, to contain an article such as a license plate 7. lt :furtherincludes a smaller envelope 8 ot the open side type to contain'aregistration c ard 9, the smaller envelope being insertable into thelarger one and attachable thereto in a manner hereinafter described toform a single package.

The larger envelope includes a seamless wall 10 over which are foldedside Haps 11 and 12, the latter overlapping the inner flap 11 and beingprovided with gum portions or 70 stripes 13 to form a seam with the flap11, the gum being applied not entirely throughout the length of the sameso as to provide a slot 14 through which the smaller envelope 8 isinserted into the larger one.

rlhe smaller envelope 8 is provided with a seal flap 15 having thereon agum strip 16 whereby the seal flap may be secured to the wall or body ofthe envelope as, Jfor example, to the outer end of the side flap 12 ofthe 80 larger envelope. There is also provided a gum stripe 17 which maybe on the smaller envelope and whereby it may be secured to the sideflap 11 of the larger envelope to seal the slot 14, thus preventingother articles, 85 such as letters, from being accidentally insertedinto or caught in the envelope while the same is passing through themail, Both of the envelopes 6 and 8 are provided with windows 18 and 19,respectively, through 90 which the name and address, on the enclosure ofthe smaller envelope, such as a registrationcard, may appear.

When the combination envelope 1s used for other enclosures, such ascatalogues and letters (Fi ure 4) the envelope 8 may be of greaterdimensions as compared with the envelope 6, the latter. being of a s1zesuitable for catalogues and the former of a s1ze sultable for letters.

It will be understood that in this type of combination envelope it isadvantageous to have the side flap 11 extend substantially to theopposite side of the envelope 6 so as to serve as a guard or protectorfor the smaller envelope 8 to prevent obstruction by the smallerenvelope of the article subsequently inserted into the larger envelope.

In the modification illustrated in Figures 5 and 6, the slot 14a,through which the small envelope is inserted, is formed in the seamlesswall 10a of the larger envelope 6a. Said slot is so located suflicientlyabove the bottom edge of the envelope 6a that the envelope 8, wheninserted, overlaps the wall 10a sufficientlyv to permit securing of theenvelope 8 to the wall 10a by means of the gum strip 17, thus sealing`the slot 14a. The smaller envelope is sealed by pasting the seal flapagainst that portion of the wall 10a immediately below the slot 14a. Thelatter is also provided with a; transparent window patch 20.

I have described what I believe to-be the best embodiment of myinvention. I do not, however, desire to limit myself to the embodimentdescribed, but what I desire to cover by Letters Patent is set forth inthe appended claims.

1. A combination 'envelope comprising a relatively large envelope of theopen end type, said lar e envelope including two overlapping side aps,means to secure said flaps to each other for part of their length toform a center seam with a slot therein, and a relatively smallerenvelope of the open side type having a seal flap, the smaller envelopehaving a seal flap and being received in said slot so that the seal flapthereof may be sealed down against the outer edge of one of the sidefiaps of the larger envelope, and means whereby the smaller envelope maybe sealed at its upper edge against the other side flap of the largeenvelope to provide a closure for said slot.

2. A combination envelope comprising a large envelope and a. smallenvelope, the larger envelope having two walls, one of said -wallshaving a slot therein through which the small envelope may be inserted,the small envelope having a seal flap to be folded overA and secured toa portion of said wall adjoining the slot, and a gum stripe on one ofsaid envelopes to secure the smaller envelope at its upper edge tothe'wall of the larger envelope to seal said slot.

3. A combination envelope comprising a larger envelopeincluding aseamless wall, an inner side flap of a width to extend substantiallyacross the seamless wall of. said envelope, an outer side flap extendingpartly over the inner side flap, means to form a partly open seambetween said side flaps to provide a slot therebetween, a smallerenvelope, the latter having a seal fla the smaller envelope beinginsertable into t e larger one through said slot so that the seal flapmay be secured to the outer flap of the larger envelope to seal thesmaller envelope, and a gum stripe on one of the envelopes whereby saidsmaller envelope may be secured to the innler ap of the larger envelopeto seal said s ot.

4. A combination envelope comprising a larger envelope of the open endtype, the latter including aseamless wall, an inner side flap, of awidth to extend substantially across the seamless wall of said envelope,an outer side Hap extending partly over the inner side flap, means toform a partly open seam between said side flaps to provide a slottherebetween, and a smaller envelope of the open.

side type, the latter having a seal flap, the smaller envelope beinginsertable into the larger one through said slot so that the seal flapmay be secured to the outer flap of the lar er envelope to seal thesmaller envelo e, an a gum stripe at the upper edge of t e smallerenvelope whereby said smaller envelope may be secured to the inner flapof the larger envelope to seal said slot, said larger envelope and saidsmaller envelope being each provided with a window, the windowsregistering with each other.

5. A combination envelope comprising a large envelope and a smallenvelope, the larger envelope having two walls, one of said walls havinga slot therein through which the smaller envelope may be inserted, thesmall envelope havin a seal flap to be folded over a portion of t e walladjoining the slot and secured thereto, and a gum stripe on the smallenvelope to secure it at its upper edge to the large envelope to sealsaid slot, said larger envelope and said smaller envelope having each awindow, the windows to register with each other.
